Why it works: Truffle and mushroom are a kitchen classic. They rank in the top 4% of all ingredient pairs, and cooks put them together in 1,900 recipes. Both carry 2,4-nonadienal, which smells fatty, green. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweetbreads
- Provide the tender, delicate meat that is the main body of the dish.
- Butter
- Browns with the flour to build the colour and nutty flavour of the brown sauce.
- Flour
- Cooked with the butter to form a roux that thickens the brown sauce.
- Broth
- Adds liquid that, with the roux, thickens the sauce to a coating consistency.
- Lardoons
- Add fat and moisture inside the fricandeaux as they cook.
- Truffles
- Add a deep, earthy aroma and luxurious flavour to the sweetbreads and garnish.
The step that matters
Browning the butter and flour. The roux must brown gently until nutty and no further; scorched flour turns bitter and dark, spoiling the sauce, while underbrowned roux leaves it pasty and raw-tasting.
